Specification of Letters IPatent.

Patented Aug. 18, 1914.

To all whom, it may concern:

Be it known that I, EUGENE T. TURNEY, a citizen of the United States,residing at Rock Island, in the county of Rock Island and State ofIllinois, have invented certain new and useful Improvements in Windingand Rewinding Mechanism for Music Sheets or Records, of which thefollowing is a specification.

This invention relates to improvements in winding and re-windingmechanism for perforated music sheets or records for use with pneumaticplaying attachments for musical instruments and one of the objects ofthe invention is to provide improved means for feeding or re-Winding thesheet or record without reversing the operation of the motor.

A further object is to provide improved means whereby the record may beshifted to any desired section of the music either forwardly ofbackwardly at will without sounding the notes.

A further object is to provide an 1mproved device of this character inwhich there is employed a pneumatic motor operated by exhausting the airtherefrom and exhaust mechanism common to all of the parts and improvedmeans whereby the suction or exhaust may be directed entirely to themotor and whereby the exhaust may be cut off from the other mechanism toprevent the operation of the latter and thus 1ncrease the speed of themotor.

A further object is to provide an improved device of this characterwhich will be simple, durable and cheap in construction and effectiveand efficient in operation.

To the attainment of these ends and the accomplishment of other new anduseful objects, as will appear, the invention consists in the featuresof novelty in the construction, combination and arrangement of theseveral parts hereinafter more fully de scribed and claimed and shown inthe accompanying drawing illustrating an embodiment of the invention andin which- Figure 1 is a detail front elevation of an improved device ofthis character constructed in accordance with the principles of thisinvention.

. Referring more particularly to the draw- 1ngs and in the presentexemplification of the invention, the numeral 15 designates a suitablesupporting frame for the record spools or rollers 16, 17, and which issupported in any desired or suitable manner Within the casing of theinstrument. S aced from one of the end members 18 of the rame 15 is anupright or partition 19 and a bushing 20 passes through the upright 19preferably adjacent the top of the frame. This bushing is preferablyprovided with internal screw threads to receive a threaded collar 21which latter is provided with an enlarged portion or head 22 located onone extremity thereof. The collar 21 forms a bearing for a shaft 23, oneend of which passes through the collar and the other extremity of whichpasses through a suitable bearing 24 secured to the upright 18 and apulley 25 is secured to the shaft 23 between the upright 19 and theadjacent end 18 of the casing, for rotation with the shaft. Theextremity of the shaft 23 which projects through the collar or bearing21 is provided with an enlarged end 26 in the form of a socket toreceive'the projecting axle 27 of the record spool 16 and this axle 27is provided with the ordinary wing or car 29, which enters a suitableslot 30 opening through the outer end of the socket whereby the rotationof the shaft 23 will rotate the spool 16. The enlarged extremity 26 ofthe shaft 23 is provided with a shoulder 31 which is adapted to restagainst the face.of the enlarged extremity 22 of the collar or bearing21 whereby the shaft 23 may be adjusted longitudinally in one directionby rotating the collar or bearing 21.

Any suitable fastening means may be provided for locking the collar orbearing 21 against rotation in its bearing. and eflicient means foraccomplishing this end comprises a locking member 32 which passesthrough a suitable aperture in the bearin 20 and engages a portion ofthe threaded periphery of the collar or bearing 21 and elastic member 33such as a coil spring or the like, is housed within the upright 19 sothat one extremity thereof will rest against the member 32 and the otherextremity against a plug or member 34 secured within the upright 19. Theother end of the spool 16 is supported in a suitable bearing 35 securedto the other upright 18 of the frame 15. Supported preferably by the endmember 18 and the upright 19 is the ordinary tracker board 36 whichlatter is arranged between the spools 16 and 17. Projecting beyond theextremities of the spool 17 are axles 37, 38. The axle 37 passes looselythrough the upright 19 and projects beyond the same, and secured to saidprojecting extremity is a gear wheel 39. The axle 38 projects through asuitable bearing or bushing 40 in the end member 18 and is provided withan enlarged extremity 41 which latter is provided with a plurality ofperipheral, V-shaped grooves 42. Pivotally supported by the outer faceof the member 18 is a brake or shoe 43 and an elastic member 44 isprovided, one extremity of which is connected to the brake or shoe 43and the other extremity to a fixed support and tends normally to holdthe brake or shoe 43 into engagement with the grooved periphery of theenlarged end 41 of the axle 38 so that the rotation of the axle 38 willcause the enlargement 41 to cut a series of grooves into the adjacentface of the brake or shoe 43 and thereby lock the spool 17 againstlongitudinal displacement.

Any suitable means may be provided for moving the brake out ofengagement with the enlargement 41 such as a button 45, which passesloosely through one of the members of the frame 15 and has engagementwith a suitable member 46 preferably in the form of a leaf spring, oneend of which is secured to the frame 15 and the other extremity isloosely connected to a A suitable and into proper position to receivethe record being unwound from the spool 16. A suitable motor 48 may beprovided for feeding or re-winding the record sheet 49. This motor isadapted to be operated by means of suction and the flexible member 50 isconnected to the suction chest of the motor for exhausting the same. Thecrank shaft 51 of the motor is connected to a flexible power shaftthrough the medium of inter-meshing gears 53. The motor is mounted uponany suitable support within the casing and is preferably spaced from theframe 15. One extremity of the flexible shaft 52 passes through anenlarged opening 54 in one of the end members 18 of the frame 15 andterminates preferably adjacent the upright 19. Secured to the shaft 52is an elongated pinion 53 which meshes with the gear 39' on the spool17. Arranged adjacent the opening 54 is a bearing which is slidablymounted in suitable guides 56. A flexible member 57 is secured by oneextremity to the bearing 55 and by the other extremity to the end member13 and tends normally to hold. the extremity of the shaft 52 in such aposition that the pinion 53 will mesh with the gear 39. A pulley 58 issecured to the shaft 52 for rotation therewith and is lo cated betweenthe upright 19 and the end member 18 of the frame. This pulley 5-8 isarranged in line with the pulley 25 on the shaft 23 and a belt 59 passesover the pulleys. This belt is preferably constructed of any suitableflexible material but preferably of some stiff material which willpermit the shaft 23 to be driven by the shaft when the pinion 53 ismoved out of engagement with the gear 39 and will slip to permit theshaft 23 to be rotated by the spool 16 when the sheet or record is beingfed from the spool to the spool 17 and w ion the pinion 53 is inengagement with the gear 39. lVith this improved construction it will beapparent that the belt will not interfere with the rotation of the shaftin the opposite direction to that in playing when it is desired to shiftthe music sheet or record to any desired portion of the music, so thatit may be replayed before the end of the piece is reached. The flexibleshaft may be shifted so as to tighten the belt 59 to drive the shaft 23in the opposite direction.

Any suitable means may be provided for moving the pinion 53 out ofengagement with the gear 39 such as a flexible member 60, one extremityof which is secured to the bearing 55, and secured to the free extremityof the flexible member is a member 61 which passes through a suitableaperture in a por tion 62 of the casing of the instrument and isprovided with a threaded extremity for the reception of a collar or nut63 below the portion 62 of the instrument casing. A slide 64 is providedwith an operating handie and is secured to the portion 62 of the casingfor sliding movement in any desired or suitable manner, preferably bymeans of screws or bolts 66 passing through suitable slots 67 in theslide and into the portion 62. This slide 64 is also provided with aslot 68 through which the member 61 passes and an inclined shoulder 69on the lower face thereof, which shoulder is adapted to engage the nutor collar 63 when the slide is moved inwardly so as to draw upon theflexible member 60 and shift the bearing 55 against the tension of theelastic member 57. When the slide is drawn outwardly so that theshoulders or inclined face 69 will move away from the nut or collar 63,the elastic member 57 together with the flexiblity of the shaft 52, willmove the elongated pinion 53 back into mesh with the gear 39.

Arranged within the casing of the instrument is a controller for themotor 48, designated generally by the reference numeral 70. Thiscontroller may be of any desired or suitable construction and may beprovided with a suitable valve 71 for governing the speed of the motorand is preferably supported by the wind trunk or passage 7 2, throughthe medium of which latter the individual pneumatics 7 3 may beexhausted and which pneumatics may be connected by suitable tubularflexible members 74 to the tracker board 36 of the instrument, in theordinary and usual manner. The wind trunk 7 2 may be exhausted by meansof two pumpers or bellows 74 located in the base of the instrument,preferably one adjacent each side thereof and to which the Wind trunkhas connection through the medium of the tubular members 7 5, preferablyleading from the extremities thereof and connecting with the respectivebellows 74, in a manner to be set forth.

Supported in any suitable manner, preferably by the base of thecontroller is a pneumatic designated generally by the ref erence numeral7 0, one member of the pneumatic being secured to the base of thecontroller and being provided with an aperture 7 0", which aperture hascommunication with the outlet 7 0 of the controller 70. The smaller endof the pneumatic preferbaly projects beyond one wall of the controlleras at 70 and said projecting end is provided with an aperture 7O whichforms an outlet for the pneumatic 7 0. A housing is supported by thefixed member of the pneumatic which is provided with a passage 7 0extending therethrough and has communication with the outlet 7 0 of thepneumatic. The other end of the passage 7O communi cates with thepassage 78 through the medium of the passage 80.

Secured to the movable member of the pneumatic 7 0 is an arm orextension 71 and connected to the extremity of said arm by one end is asuitable elastic member 71", such as a coil spring or the like. To theother extremit of the elastic member is connected an ad usting device 71in the forman of a bolt which passes through a suitable support 71", andan adjusting nut or collar 71 is adapted to engage the bolt 71 on theopposite side of the support 71 through the medium of which the tensionof the elastic member 71 may be adjusted. The specific construction,however, of this governor mechanism forms the subject matter of myco-pending application Serial No. 454,100, to which reference may be hadfor a description of the parts not specifically described herein.

The controller 7 O is provided with an extension 7 6 shown more clearlyin Figs. 6 and 10 of the drawings, and this extension is provided with aplurality of passages 7 7 7 8, which communicate with the respectivepassages 7 9, 80 in the controller 70. A tubular member 81 hascommunication with one of the passages in the extension, preferably thepassage 77, and to the extremity of this tubular member is secured oneextremity of the flexible tubular member 50, which latter hascommunication with the suction or ex-- haust chamber of the motor 48. Asimilar tubular member 82 has communication with the other passage 78 inthe extension 76 and a tubular member 83 is connected by one extremityto the tubular member 82 and by its other extremity to a suitablechamber 84, and which latter has communication with a valve box 85supported within the casing, through the medium of a tubular member 86,and said chamber 84 also has communication with one of the pumpers orbellows 74, whereby through the operation of the respective pumper orbellows 74 the suction chamber of the motor 48 will be exhausted throughthe controller 70 through the passages 77, 79, 80 and 78. Similartubular members 87 connect the valve box 85 respec tively with aconnection or junction box 88 to which latter the tubular membersleading from the wind trunk 72 are connected. A tubular member 89,similar to the member 86, also leads from the valve box 85 and connectswith a casing 90, which latter also has communication with one of thepumpers or bellows 74. WVith this improved construction when the pumpersor bellows 74 are operated, the wind trunk 7 2 will be exhausted throughthe valve box 85 causing the air to flow through the tubular members 75,87, and junction box 88 into the valve box in the direction as indicatedin Fig. 8

and out of the valve box to the pumpers or V bellows 7 4 through thetubular members 86, 89 in the direction indicated in Fig. 8. The valvebox 85 is provided with a partition 91 having an opening 92 adapted tobe closed by the valve or closure 93, which latter slides in suitableguides 94 inthe valve box. The partition 91 and valve 93 are locatedbetween the extremities of the tubular members 87 where they connectwith the valve box and the acent extremities of the tubular members 86and 89, so that the suction created by the pumpers or bellows 7 1- willtend to hold the valve 93 against its seat when closed. The va vs 98 isadapted to be moved to cover or uncover the opening 92 in the partition91 in any suitable manner but preferably by means of a rock shaft 95which is mounted in suitable bearings 96 preferably secured to theportion 62 of the casing. This rock shaft 5 is provided with an arm 97,the extremity of which is connected by means of a suitable flexiblemember 98 through the medium of a fastening device 99 to the valve 98 sothat when the shaft 95 is rocked to raise the arm 97, the valve 93 willbe raised to uncover the opening 92 to form communications between thewind chest or trunk 72 and the pumpers or bellows 7 1 through the mediumof the tubular members 86, 89, 87 and 75. V7 hen the shaft 95 is rockedto lower the arm 97, the valve 93 will close prefe ably by gravity so asto cut off the pumpers or bellows 7 1 from the wind chest for a purposeto be set forth.

The valve 93 is adapted to be opened when the music sheet is being fedto play a tune and any suitable means may be provided for shifting thevalve to establish communication between the wind trunk and the bellowsor pumpers or when the pinion. is moved into engagement with the gear Asuitable and efficient means for accomplishing this purpose comprises ashoulder 100 on the slide 6 1 adjacent the rear extremity thereof, whichlatter is located in proximity to the shaft The shaft is also providedwith a crank arm 101 which depends below the shaft and stands within thepath of the forward movement of the shoulder 100 so that when the slide6 1- is moved outwardly by the handle to cause the in clined face ofshoulder 69 thereon to move out of engagement with the collar or nut 63on the member 61, the shoulder 100 will engage the arm 101 to rock theshaft 95 and raise the arm 97 to shift the valve 93 away from theopening 92, but the movement of the face or shoulder 69 out ofengagement with the nut 68 will occur before the shoulder 100 engagesthe arm 101. When the slide 64c is moved in the opposite direction, theshoulder 100 will move away from the arm 101 to permit the valve 93 toclose and thereby cut off communication of the wind trunk 72 from thebellows or pumpers 7 1.

if desired, suitable means may be provided for assisting in closing thevalve 98 should the latter for any reason fail to open ate or stick.This may be accon'r-plished by means of a shoulder 102 provided'on theextension of the slide 64 and which is located on the side of the arm101 opposite to that on which the shoulder 100 is located and is sodisposed with relation to the inclined face or shoulder 69 as to engagethe arm 101 when the inclined face or shoulder 69 engages the collar ornut 63, if the arm 101 has not moved out of the path of the movement ofthe shoulder 102 by the closing of the valve.

Arranged within the extension 76 of the controller '70 is a passage 103which forms communication between the passages 77, 78, and a suitablevalve 10 1 is provided for closing the connecting passage 103. lhisvalve is provided with a cooperating valve seat 105 and a stem 106, oneextremity 107 of which projects below the extension 76 and is adapted tobe engaged by a projection 108 on a collapsible pneumatic 109 which issupported preferably from the extension 7 6 and has communication withthe wind trunk 72 through the medium of a passage 110 and the tubularmember 111.

In op ration when the valve, 93 uncovers the opening 92 in the valve box85 and the pumpers or bellows 74. are operated, the suction will be fromthe tracker board through the flexible tubular members 741 through theindividual pneumatics 7 3, wind chest or trunk 72, tubular members 7 5,junction box 88 and tubes 87 through the valve box 85 through thetubular members 86 and S9 and to the pumpers or bellows 7-1. lhis degreeof suction may be varied for the motor 18 at the will of the operator byadjusting the valve 71 in the controller in any desired or suitablemanner, preferably by means of an operating lever designated generallyby the reference numeral 112. When the valve 71 is adjusted from itsseat in the controller, the suction will be exerted upon the motor asthrough the tubular member 50 into the passage 77 through the tubularmember 81, through. the passage 79 in the controller out of thecontroller through regulator pneumatic to the passage 90, from thepassage to the passage 7 8, through the regulator or governor pneumatic7m to the tubular members 82, 83, and through the valve box through thetubular members 82, 88, chamber 8 1 and bellows or pumpers 7 1. lVhenthe pinion 53 is in a position to feed the record from the spool 16 tothe spool 17 in order to sound the notes of the instrument, the air willtake the course above described, that is, will pass through regulatorpneumatic 70 and around the valve 10 1, which latter normally closes thecommunicating passage 103.

When it is desired to rewind the record. to replay a certain portion ofthe music or for the purpose of applying a new record, it is desirableto shut off the suction from the wind trunk 72 to prevent the operationof the individual pneumatics and also the sounding of the notes duringthis re-winding operation. In order to accomplish this result thecollapsible pneumatic 109 is provided and when the re-winding mechanismis shifted, air will be admitted to the pneu matic 109 from the chest 72through 111, 110, which movement will cause the projection 108 to moveaway from the valve seat 105 to permit the valve 101 to open or drop.Vhen this valve 104 is unseated, there will be a direct communicationfrom the pumper o1 bellows Tel to the motor 48, through the passage 103,thereby causing the exhaust to operate directly upon the motor. Thisoperation is designed to be effected when the shaft 52 is shifted todisengage the pinion 53 from the gear 39 so that the motor may be run athigh speed to re-wind the record. Vhen the slide 64 is shifted todisengage the pinion from the gear 39, the valve 93 will also beoperated or permitted to assume a position to close the opening 92 andwhen the valve is closed all communication from the wind chest 72 to thebellows or pumpers 74 will be cut off and the latter may be operated atany desired speed to increase the suction in the motor and therebycontrol the speed of the motor. lVhen the slide 64 is again shifted ormoved in the opposite direction the valve 93 will open in the manneralready set forth and the pinion 53 will again assume a position in meshwith the gear 39 in the manner set forth, so that when the communicationbetween the wind trunk and the various individual pneumatics 73 isreestablished to the pumpers or bellows 74, the sheet or record will bemoved in a direction to cause the notes to be sounded. The valve 93 isalso adapted to be adjusted at the will of the operator to cut off thesuction from the pneumatic actions to permit the sheet or record to bemoved in the direction of its playing movement without sounding thenotes. With this improved construction it will be apparent that theoperation of the motor is absolutely under the control of the operatorand by the provision of the stiff flexible belt 59, the shaft 23together with the spool 16 will be permitted to rotate in a directionopposed to the direction of movement of the belt 59 so that the recordmay be fed from the spool 16 onto the spool 17 by the tension of therecord itself and the belt 69 will slip during the feeding movement ofthe record. When the pinion 58 is moved out of engagement with the gear39, the belt 59 will be tightened so that the shaft 23 and spool 16 willbe rotated in the opposite direction or in the direction of the movementof the belt withoutreversing the driving shaft and which direction ofrotation of the shaft 23 will re-wind the rec- 0rd from the spool 17 tothe spool 16. The belt 59, being constructed of a suitable stiffmaterial, when loosened by the engagement of the pinion 53 of the gear39 will hold itself in such a position as to permit the pulleys 25 and58 to rotate freely without creating too much friction thereon.
